Can I use AR-10 or AR-15 magazines with your chassis?

A chassis (or bottom metal) does not determine whether you can use AR Magazines with a bolt action rifle. AR Magazines do not sit high enough against the bottom of bolt actions to make it feed properly.

There are only a few Bolt Action rifle platforms that allows the use of AR magazines, and that is the Mossberg MVP, and a specific model of the Ruger American.

So our chassis for the Mossberg MVP are made to use AR magazines exclusively. For the Ruger American, you need the specific Ruger American compatible rifle, and choose our chassis compatible with the AR magazines.

Are there any other mags out there that will work with the LSS 308 length chassis? I was disappointed to find that had to load to a shorter overall length to fit my CTR's magazine. I want a mag that allows a longer COAL.

Just to argue I have built a Remington 700 223 running slightly modified ptg at 15 bottom metal pmags and a mini m16 extractor. Now in the process of designing a near drop-in control round feed bolt for the 700. (Will require a side bolt release to work)
